Holland Shielding Systems B.V. has experience in all types of EMC anechoic chambers and designs.
Our Anechoic Chambers are constructed as shielded rooms. All over the walls and the ceiling, absorbing materials and/or ferrite tiles are attached. The Anechoic Chambers show superb shielding performance and are mainly applied in EM emission testing according to commercial and military standards.
The Anechoic Chambers are used to perform compliant radiated immunity tests in accordance to EMC-standards such as IEC / EN 61000-4-3.
They provide a full compliance immunity test site for the frequency range of 26Mhz to 18GHz.
Also suitable for future free space emission test, pr EN 50147-3.
We can also build open area test sites.
